Beschreibung
Zusammenfassung:	A method for producing a substantially desulfurized hydrocarbon fuel stream at temperatures less than 100°C including providing a nondesulfurized fuel cell hydrocarbon fuel stream and passing the fuel stream through a sequential sulfur adsorbent bed system containing at least one selective sulfur adsorbent and a calcium exchanged zeolite to produce a substantially desulfurized hydrocarbon fuel stream. L'invention concerne un procédé pour produire un flux sensiblement désulfuré d'un combustible à base d'hydrocarbures à des températures inférieures à 100 °C; il consiste à former un flux de combustible à base d'hydrocarbures pour une pile à combustible non désulfuré et à faire circuler le flux de combustible dans un système de lit d'adsorbant séquentiel contenant au moins un adsorbant de soufre sélectif et un zéolite à calcium échangé pour produire un flux de combustible à base d'hydrocarbures sensiblement désulfuré.
